Laboratory tests have shown that the major wastewater streams produced during oil shale retorting can in principle be treated to a quality suitable for reuse within the plant. The wastewater stream condensed from the retort gases, here called the gas condensate, contains primarily dissolved gases (NH3, CO2 and some H2S) and organics as contaminants. In batch stripping tests it was found that the organics, which may be present at concentrations of up to 5,000 mg/l measured as COD, are volatile and can be stripped along with the ammonia down to about 500 mg/l COD. Retort waters, or wastewater streams that …

Material balance calculations for several proposed oil shale processes have been made and show that water requirements vary from 2 to 5 times the product oil rate. Wastewater is produced at from one-third to 1.5 times the product oil rate and may be treated and used to offset the source water requirement. Water management schemes are used to show the degree of treatment required for each type of wastewater. Conceptual designs of treatment trains, based on laboratory investigations of reverse osmosis, resin adsorption, biological oxidation and steam stripping processes on actual wastewaters, show that water management costs range from 60¢ …
